Lemon bars recipe


For bright citrus flavor, successful lemon bars depend on ample amounts of fresh lemon juice, yes, but also a generous amount of lemon zest, which provides round, floral notes. We used four lemons for our lemon curd filling, which yielded a whopping ⅔ cup of juice and ¼ cup of zest. The other major ingredient for lemon curd is eggs, and lots of them. Two whole eggs and seven yolks gave us a luxurious curd with good thickening properties. To tame the curd’s pucker power and make it ultracreamy, we added a small amount of heavy cream and some butter. Confectioners’ sugar contributed a tender texture to the crust. We found that it was important to pour the warm filling over a still-hot crust to ensure that the filling cooked through evenly; you can prepare the filling while the crust bakes. Humidity tends to make the sugar melt and turn splotchy, so if you live in a humid climate dust the lemon bars with the confectioners’ sugar right before serving.

  • Yield: 16 bars


  • 1¼ cups (6¼ ounces) all-purpose flour
  • ½ cup (2 ounces) confectioners’ sugar
  • ½ teaspoon salt
  • 8 tablespoons unsalted butter, cut into 8 pieces and softened
  • 2 large eggs plus 7 large yolks
  • 1 cup (7 ounces) plus 2 tablespoons granulated sugar
  • ¼ cup grated lemon zest plus ⅔ cup juice (4 lemons)
  • Pinch salt
  • 4 tablespoons unsalted butter, cut into 4 pieces
  • 3 tablespoons heavy cream
  • Confectioners’ sugar
How to Make It
  1. Adjust oven rack to middle position and heat oven to 350 degrees. Make foil sling for 9-inch square baking pan by folding 2 long sheets of aluminum foil so each is 9 inches wide. Lay sheets of foil in pan perpendicular to each other, with extra foil hanging over edges of pan. Push foil into corners and up sides of pan, smoothing foil flush to pan. Grease foil.
  2. For the Crust
  3. Process flour, sugar, and salt in food processor until combined, about 3 seconds. Sprinkle butter over top and pulse until mixture is pale yellow and resembles coarse meal, about 8 pulses. Sprinkle mixture into prepared pan and press firmly into even layer. Bake until crust begins to brown, about 20 minutes, rotating pan halfway through baking. (Crust must still be hot when filling is added.)
  4. For the Filling
  5. Meanwhile, whisk eggs and yolks together in medium saucepan. Whisk in granulated sugar until combined, then whisk in lemon zest and juice and salt. Add butter and cook over medium-low heat, stirring constantly, until butter is melted and mixture thickens slightly and registers 170 degrees, about 5 minutes.
  6. Immediately strain mixture through fine-mesh strainer into bowl and stir in cream. Pour warm lemon curd evenly over hot crust. Bake until filling is shiny and opaque and center jiggles slightly when shaken, 10 to 15 minutes, rotating pan halfway through baking.
  7. Let bars cool completely in pan on wire rack, about 2 hours. Using foil overhang, remove bars from pan. Cut into 16 pieces and dust with confectioners’ sugar before serving. (Bars can be refrigerated for up to 2 days.)
